Unexspected end of JSON input

Hey guys, I recently updated from API Plugin v6.1.1 to v7.0.3 and got into trouble with the new handling of request body. I try to extract the body of my request with const body = await request.readBodyJson(); Once this call is executed I get the error SyntaxError: Unexpected end of JSON input. My JSON looks the following

{
    "action": "app_membership.went_invalid",
    "data": {
        "created_at": 1697500033,
        "expires_at": null,
        "renewal_period_start": null,
        "renewal_period_end": null,
        "quantity": 1,
        "status": "canceled",
        "valid": false,
        "cancel_at_period_end": false,
        "license_key": null
    }
}

{
    "action": "app_membership.went_invalid",
    "data": {
        "created_at": 1697500033,
        "expires_at": null,
        "renewal_period_start": null,
        "renewal_period_end": null,
        "quantity": 1,
        "status": "canceled",
        "valid": false,
        "cancel_at_period_end": false,
        "license_key": null
    }
}

I don't know how to deal with this error as I already tried everything I know to fix this. Any suggestions or ideas would be recommended 🙂

Solution:

You shouldn't read the body twice 😅

You have a leading comma at license_key, which is a syntax error in JSON, and you’re not closing the top brace ({})

Good point. I will correct this is only a Copy & Paste Error here sorry 😅 This was not the error, I fixed the example JSON of my post as I was using the "correct" version on Postman Funny thing seems like if (((await request.readBody()) as any).action !== 'app_membership.went_invalid') return response.badRequest(); works but when I want to access .data I get an exception

Well that's a good point! You are absolutely right, I transformed my code (In v6 I accessed request.body and so on) and now it's working 😄 Thx :this:
